Physics Sandbox
🔬 Sandboxels
A falling-sand physics simulation with over 500 materials. Water flows, sand falls, lava melts through rock, ice freezes nearby water. There is no recipe book — you learn by watching what materials do to each other. The closest thing on this list to Infinite Craft's "combine two things and see" loop, except the answer is physics instead of word meaning.
